摘要
针对充电桩存在的谐波含量高、功率因数低的问题,提出了一种三相三电平VIENNA整流器,研究了整流器的控制系统结构和控制策略,提出了一种电压电流双闭环的控制结构,采用了电流滞环比较控制和中点电压平衡控制方法.通过PSIM仿真软件仿真验证方案的可行性,稳态运行时网侧THDi仅2.23%,功率因数达到99.93%.
In view of the problem of high harmonic content and low power factor in charging pile, this pa- per proposes a three-phase and three-level VIENNA rectifier. The control system structure and control strategy of the rectifier are studied. The voltage and current dual closed-loop control structure is proposed by using controlling method of the current hysteresis comparison and neutral point voltage balance. The feasibility of scheme is verified by PSIM simulation software. The network side of THDi is only 2.23% un- der the steady-state operation, and the power factor is nearly 99.93%.
